OFFICE-LEDGER.

Specification of Letters Patent.

Patented Oct. 19, 1920.

Application filed December 30, 1919. Serial No. 348,379.

To all whom it may concern 7 Be it known that I, JACOBUS FRANoIsoUsGnnARDUs Jonenrmn, merchant, a subject of the Queen of the Netherlands,residing at Schiedam, the Netherlands, 43 Lange Haven, have inventedcertainnew and useful Improvements in Ofiice-Ledgers, of which thefollowing is a specification.

This invention has reference to ledgers and the like and it has relationto ledgers and the like whose covers are provided on one or more oftheir edges with indicators or column markers that comprise stripsdivided in accordance with the columnar ruling and bearing indicationsof the purpose of the ruling.

In such ledgers and the like the indicators or column markers have beenmounted on the covers so that they can be folded within the book; it isfound that such indicators 01' column markers wear out'rapidly and breakat the hinge; they also sufier from the disadvantage that they cannot beplaced in or out of use without it being necessary to open thecover orturn over the pages.

The present invention overcomes the objections that pertain to the knownconstruction and in accordance therewith an indicator or column marker(or indicators or column markers) is mounted on the cover so as to becapable of sliding movement in relation thereto.

The accompanying drawing is partly a plan view, apart being broken away,of the cover of a ledger.

The indicator or column marker 1' has a portion 2 that is divided inaccordance with the columnar ruling of the pages of the book. Theindicator or column marker 1 is in one piece with a part3 havingextensions or lugs 4 (only one is shown). The inside of the cover 5 ofthe book is provided with a pocket 6 and within the pocket 6 with blocks7 (only one is shown). The parts 3 and 4 of the indicator or columnmarker are always contained within the pocket 6 and the indicatororcolumn marker as a whole can be slid in and out thereof, the outwardmovement being limited by contact of the extensions 4 with the blocks 7.8 is a tab by which the indicator or column marker can be moved inwardor outward of the pocket 6. The indicator or column marker can also bemoved inward of the pocket 6 when r the book is open by pressure on thepart that extends beyond the pages of the book.

The tab 8 instead of being placed in the position in which it is shownmay be attached to the indicator or column marker so that it protrudeseven when the book is closed and the indicator or column marker is inits inward position.

If desired, a number, letter or other sign may be placed on theindicator or column marker atthe top 'ofeach division, as'also at thetop of the corresponding column of the age. 7

I aving fully described my invention, what I claim as newand desire tosecure by Letters Patent is 1. In combination with a ledger, a columnmarker slidable on the inside of the cover of the ledger so as to beextended above the upper edges of the cover to coact with the ledger,and coactive means on the inside of the cover and on the marker forlimiting the sliding movement thereof.

2. In combination with a ledger, a marker slidable on the inside of thecover of the ledger and provided with a columnar ruling longitudinallyof the front face near the upper edge thereof and coacting with theleaves of the ledger when the marker is extended above the upper edgesof the cover, and coactive means on the inside of the cover and on themarker for limiting the inward and outward sliding movement thereof. i v

3. In combination with a ledger, blocks secured'to the inside cover ofthe ledger at the side edges thereof, a columnar marker slidable on the.inside of the cover and lateral lugs at 'the opposite sides of themarker for coacting with the blocks for limiting the outward slidingmovement of the marker.

4. In combination with a ledger, a pocket on the inside of the cover ofthe ledger, opposed blocks secured to the inside of the cover near theside edges thereof, a column marker slidable inside of the pocket and retained by the pocket, and lateral lugs on the opposite sides of themarker for coacting JACOBUS FRANCISCUS GERARDUS JONGEPIER.
